Won’t say I gave up on the P38/51, but I haven’t used mine in 25 years.
The can opener on a SAK is much better.
But after a series of events, we now have multiple hand operated “real” can openers.
Including ones left in the camping/survival gear permanently.
I’ve really come to appreciate the side cut openers that allow you to use the can lid as an actual lid to cover the can.
